FERC-NERC September 2011 Outage Report Calls for Improved Planning
The September 2011 blackout that left 2.7 million consumers in Southern California, Arizona and Baja California without power stemmed from operating in an unsecure state due to inadequate planning and a lack of observability and awareness of system operating conditions on the day of the event, a joint report by the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC) found.
The report was released today after a nearly eight-month inquiry and recommends that transmission operators and Balancing Authorities improve how they plan for operations to account for the status of facilities outside their individual systems, the effects of external operations on their own systems and how operation of transmission facilities under 100 kV can affect the reliability of the bulk power system.
